Synchronize bdem.xsd and balber.xsd with generated types
Synchronize bdem.xsd and balber.xsd with generated types

This commit makes the definitions of the types
`balber::BerDecoderOptions` and `balber::BerEncoderOptions` available
from their respective components consistent with those provided by the
`balber.xsd` and `bdem.xsd` schemas. This commit has a counterpart in
the `bde-classic` repository.

Deployment Risks:
Per the linked DRQS, BAS services load `bdem.xsd` when loading their
service configurations. Changing the defaults of the codec options in
`bdem.xsd` may alter the corresponding default values in BAS services.
Adding the new optional field has little risk.

Test Plan:
Not worthwhile to automate. Visually confirmed consistency.
